Commit 5f12f4ff9078455cad9d4806da01f570553a5bf9 made suppressing inline namespaces when printing typenames default to true. As we're using the inline namespaces in LLDB to construct internal type names (which need internal namespaces in them to, for example, differentiate libc++'s std::__1::string from the std::string from libstdc++), this broke most of the type formatting logic.
